1. your dogs need to be hams
2. hams who love cookies
3. hams who would sell their tail for a cookie
4. hams must be trained to sit/stay while mommy does strange things to their heads
5. actually there are no cookies involved in the process, but they know it's coming afterwards
6. did i mention camera hams?

LOL All of mine are camera hams...and love cookies...but they also love to pull things offa each others' heads... It's a little-known talent (I certainly didn't know they had it. I only discovered it when I started putting things on their heads...) I guess I'll have to try again tomorrow with only one at a time in the room... I think they're really gonna hate me after this...
